Preventive Maintenance Procedures
P/N 508138 Rev. J
3.2 PRE-UF PUMP FILTER
Replace the Pre-UF Pump Filter (part number 672574).
Caution: Do not attempt to disassemble the Pre-UF Pump Filter. If not
properly reassembled, the Pre-UF Pump filter may leak. A leak in the
hydraulic system at this location may affect the operation of the machine or
cause fluid loss from the patient.
3.3 UF PUMP CHECK VALVES
Caution: Ensure each check valve is oriented correctly to allow fluid flow in
the proper direction.
Replace the UF Pump Output check valves. There are two check valves at the UF pump
output. One is at the UF pump itself. The other is downstream at the UF Sample Port.
3.4 DIAPHRAGM PUMPS
Rebuild the UF, Bicarbonate and Concentrate diaphragm pumps as described in
Sections 4.1 and 4.2.
